High Efficiency Iris Feature Extraction Based on 1-D Wavelet Transform
Ching-Han Chen, Chia-Te Chu · 2005
In this paper, a new technique is proposed for high efficiency iris recognition, which adopts 1-D wavelet transform to extract iris texture feature and probabilistic neural network (PNN) to recognize iris pattern. A c omparative experiment of existing methods for iris recognition is evaluated on CASIA iris image databases. The results reveal the proposed algorithm possesses a very high efficiency and low dimensionality of feature vectors than existing methods.
